Aug. 16, 1932. c. F. CARTER ELECTRICAL CONNECTER Filed May 19, 1930Inventor fhnewejf'dmzer A tiomey Patented Aug. 16, 1932 UNITED STATESPATENT OFFICE ELECTRICAL CONNECTER Application filed May 19, 1980.Serial No. 453,698.

This invention relates to new and useful improvements in electricalconnecters for electrical conductors. The principal object of thisinvention is to provide a connection for conductor terminals whereby afirm and intact connection may be made.

Another important object of the invention is to provide a connecterwhich is capable of connecting conductor terminals in a quick andlasting relation.

Several other important objects and advantages of the invention willbecome apparent to the reader as the description of the inventionproceeds hereinafter.

In the drawing Figure 1 represents a side elevational view of aconnecter enclosed by flexible tubing.

Fig. 2 represents a side elevational view of the connecter partlywithdrawn showing the tubein section.

Fig. 3 represents a longitudinal sectional view through the connectertaken substantially .on the line 33 of Fig. 2 with tube sectionsremoved.

Fig. 4 is an enlarged fragmentary sectional view disclosing certainparts of the connecter.

Fig. 5 represents a perspective view of the expansible bushing.

Fig. 6 represents across sectional view of the bushing takensubstantially on the line 6-6 of Fig.5.

Referring to the drawing,.where1n-l1ke numerals designate like parts, itcan be seen that numerals 5 and 6 represent adjacent ends vided with theusual insulating jac et '7,

The novel socket construction generally referred to by the numeral 8 isrovided for the conductor terminal 5, while the plug structure 9, isprovided for the conductor terminal 6. The socket structure 8 isprovided with a pocket 10 extending inwardly from one end thereof toreceive the conductor terminal 5, and securin means 111s placed in thispocket 10 to reta n the conductor ter minal properly connected to thesocket structure 8. v

Of course, this must be a current conductive connection. A pocket 12extends mwardly from .the opposite or outer end of of a pair ofconductors which may be pro the socket structure 8 and terminates at itsinner end before communicating in the pocket 10. A pin 13 is disposedtransversely thru the socket structure 8 at the inner end of the pocket12. The plug structure 9 includes a cylindrical body 145 provided with apocket 15 at one end to receive the conductor terminal 6, wherein theterminal is secured by some of the aforementioned means 11.

The outer end of the body 14 is provided with an elongated toothedextension 16, which in itself is provided with a reduced and threadedextension 17, the portion between the outer ends of theextension 16 andthe extension 17 being tapered as at 18. i

Fig. 5 discloses the bushing structure which .is employed in conjunctionwith the aforementioned parts. This bushing is tubular and is denoted bythe numeral'19. Slits 20 extendinwardly from one end of the bushing andterminate inwardly of the oppositeend thereof, while slits 21 extend ininwardly from the opposite end of the bushing and terminate inwardlyfrom the first-mentioned end of the bushing, the latter slits bein ininterlapping relation with respect to the rstmentioned slit, as in themanner clearlyshown in Fig. 5.

Numeral 22 discloses a stationary internally threaded bushing providedwith notches 23 at one end to receive the aforementioned pin 13 when thebushing 22 is inelosed with-- in the pocket 12 as in the manner -shownin Fig. 3. The opposite end of thebushing 22 is tapered as at 24 forengagement within the internally beveled adjacent end of the bushing 19.when the bushing 19 is properly disposed over the threaded extension 17.The opposite end of the bushing 19 is I also internally beveled so as toengage against the tapering portion 18 of the body 14. After the partsare assembled on'the plug structure 9 as in the manner shown in Fig. 4,the same is inserted into the pocket 12 of the socket. structure 8 andby rotating the plug 9, the body 14 will be fed toward the bushing 22;during which maneuver the bushing 19 expands and confines against themner s1de of 10( l the pocket 12, in snug contact so as to firmlyconnect the plug body 14 to the socket structure 8.

Numerals 25 and 26 represent flexible tube sections which are engagedover the socket structure 8 and plug structure 9 respectively. Byengaging the shapes and ends of these flexible sections, in abuttingrelation as shown in Fig. 1, the entire connection will be fully coveredand protected.

While the foregoing specification sets forth the invention in definiteterms, it is to be understood that numerous changes in the shape,

size and materials may be resorted to without departing from the spiritand scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is A connecterfor electrical conductors comprising a socket having an axially disposedchamber, a pin extending diametrically through the chamber, a plugincluding a body, an axially disposed threaded extension on the body,the body having a bevelled seat tapering toward the extension, a bushingthreaded on the extension having a tapered inner end defining a seat, anexpansible sleeve disposed on the extension and having its ends fittedon the first and second mentioned seats, the plug being slidable in thesocket, said bushing having a diametrically, extending slot on its outerend for receiving the pin in the socket, whereby upon turning movementof either the socket or the plug, the bushing can be threaded on theextension for expanding the sleeve.

In testimony whereof I afiix my signature.

CLARENCE FREEMONT CARTER.
